Playing F4V files on a PS3
F4V files are high definition Flash Video files that you will find on websites like Youtube, Hulu, DailyMotion etc. These files won't play natively on the PS3 or even using streaming programs such as Tversity (no ffdshow codec for it) or PS3 Media Server.
Looking at the structure of this files using Gspot, they are using avc1 codec (H.264/MPEG-4 AVC). By simply renaming the files to *.mp4, these then showed up on Tversity/PS3 Media Server etc and could be played natively on the PS3.
